The puncture device in the related art drives the puncture needle to linearly move through the linear motion mechanism to realize needle insertion operation, and the adopted linear motion mechanism is generally a conventional linear motor or a screw transmission mechanism. Although the moving mechanism can drive the puncture needle to linearly move, the moving stroke of the moving mechanism needs to be consistent with the moving stroke of the puncture needle, that is to say, the whole length of the moving mechanism cannot be further reduced under the condition that the moving stroke of the puncture needle is ensured, so that the volume of the puncture device can be larger.

As shown in fig. 1 to 2, an embodiment of the present utility model provides an automatic lancing device for robotic lancing operation, comprising: the puncture needle comprises a supporting plate 1, a primary transmission assembly 2, a secondary transmission assembly 4 and a puncture needle fixing piece 3; wherein, the liquid crystal display device comprises a liquid crystal display device,

the primary transmission assembly 2 comprises a linear motor 21, a push rod 26, a gear 22, a fixed rack 23 and a movable rack 24;

the linear motor 21 is fixedly arranged on the supporting plate 1, the linear motor 21 is connected with the push rod 26, the gear 22 is rotatably arranged on the push rod 26, and the rotation axis of the gear 22 is perpendicular to the axis of the push rod 26; the fixed rack 23 and the movable rack 24 are respectively meshed with two sides of the gear 22, the fixed rack 23 is fixedly connected with the supporting plate 1, and the movable rack 24 is in sliding connection with the supporting plate 1;

the secondary transmission assembly 4 is arranged on the side surface of the movable rack 24 and comprises a first pulley 42, a second pulley 43, a belt 41 and a connecting piece 6, wherein the first pulley 42 is rotationally connected with the first end of the movable rack 24, the second pulley 43 is rotationally connected with the second end of the movable rack 24, and the belt 41 is sleeved on the first pulley 42 and the second pulley 43;

the lower part of the belt 41 is fixedly connected with the supporting plate 1 through the connecting piece 6, the upper part of the belt 41 is fixedly connected with the puncture needle fixing piece 3, and the puncture needle fixing piece 3 is used for fixing the puncture needle 5.

In the embodiment, the amplification of the movement stroke is realized mainly by the cooperation of the primary transmission assembly 2 and the secondary transmission assembly 4 which are arranged on the supporting plate 1. The pallet 1 has a bottom wall and two side walls, which are located on both sides of the bottom wall. The primary transmission assembly 2 is used as a primary stroke amplifying mechanism and mainly comprises a linear motor 21, a push rod 26, a gear 22, a fixed rack 23 and a movable rack 24. The linear motor 21 may be fixed to the bottom wall of the pallet 1, and the fixed rack 23 may be fixed to a side wall of one side of the pallet 1. The long side of the fixed rack 23 is parallel to the needle feeding direction of the puncture needle 5, and the fixed rack 23 can be fixedly connected with the side wall and the bottom wall of the supporting plate 1 through bolts, so that the connection between the fixed rack 23 and the supporting plate 1 is stable enough. The push rod 26 is connected with the output end of the linear motor 21, and can drive the push rod 26 to reciprocate linearly under the action of the linear motor 21.

At one end of the push rod 26 far from the linear motor 21, a gear 22 is arranged, the gear 22 can be connected with the push rod 26 through a rotating shaft 221, the axis of the rotating shaft 221 is perpendicular to the axis of the push rod 26, the gear 22 can rotate on the rotating shaft 221 in a fixed shaft mode, and one side of the gear 22 is meshed with the fixed rack 23. The movable rack 24 is slidably disposed on the pallet 1, and a convex structure is provided in the middle of the pallet 1, the movable rack 24 is disposed on the convex structure and has the same height as the fixed rack 23, and the convex structure in the middle of the pallet 1 serves as a sliding support for the movable rack 24. The movable rack 24 can reciprocate on the supporting plate 1 in a driving way, the movable rack 24 is meshed with the other side of the gear 22, the long side of the movable rack 24 is parallel to the long side of the fixed rack 23 in the moving process, the vertical distance between the long side and the long side is constant, and the moving direction of the movable rack 24 is parallel to the needle feeding direction of the puncture needle 5. When the push rod 26 pushes the gear 22 to move linearly on the pallet 1, the gear 22 also rotates on the fixed shaft during the linear movement because the two sides of the gear 22 are respectively meshed with the fixed rack 23 and the movable rack 24. Because the movable rack 24 is in sliding connection with the supporting plate 1, the rotation of the gear 22 drives the movable rack 24 to linearly move on the supporting plate 1, and the movement stroke of the gear 22 can be amplified by the structure.

In the initial state (before the puncture needle 5 is inserted into the needle), the fixed rack 23 and the movable rack 24 are in a staggered structure, the fixed rack 23 is fixed at the lower part of the supporting plate 1, the gear 22 is close to the upper end of the fixed rack 23, the movable rack 24 is positioned at the upper part of the supporting plate 1, the gear 22 is close to the lower end of the movable rack 24, along with the needle inserting operation of the puncture needle 5, the movable rack 24 moves to the lower part of the supporting plate 1 in a straight line, and when the movable rack 24 is at the maximum travel point, two ends of the movable rack 24 can be almost flush with two ends of the fixed rack 23. As shown in fig. 1, 2 and 4, in the primary transmission assembly 2, when the gear 22 moves linearly by 10mm (i.e., the push rod 26 moves linearly by 10 mm), the rotational displacement of the actual gear 22 is 20mm, and since the movement of the movable rack 24 is rotationally driven by the gear 22, the movement stroke of the movable rack 24 is 20mm. In this embodiment, the primary transmission assembly 2 is used to amplify the motion stroke of the linear motor 21 (push rod 26), and the amplified motion stroke is actually twice that of the linear motor 21 (push rod 26). The principle of the transmission assembly for realizing the motion stroke amplification is similar to that of a movable pulley.

The secondary transmission assembly 4 is mainly composed of a first pulley 42, a second pulley 43, a belt 41 and a connecting piece 6 as a secondary stroke amplifying mechanism. The first pulley 42 and the second pulley 43 are disposed on the side of the movable rack 24, and the direction of the two are also parallel to the needle insertion direction of the puncture needle 5. The first pulley 42 is connected with the first end of the movable rack 24, the second pulley 43 is connected with the second end of the movable rack 24, the first pulley 42 and the second pulley 43 can rotate in a fixed shaft mode, and the belt 41 is sleeved on the first pulley 42 and the second pulley 43. The linear movement of the belt 41 will drive the first pulley 42 and the second pulley 43 to rotate, and similarly, the rotation of the first pulley 42 and the second pulley 43 will drive the belt 41 to move linearly. The belt 41 is divided into an upper portion located on a first side of the first pulley 42 and the second pulley 43 and a lower portion located on a second side of the first pulley 42 and the second pulley 43. The connecting member 6 is used to connect the lower portion of the belt 41 with the pallet 1 such that when the first pulley 42, the second pulley 43 and the belt 41 as a whole are linearly moved with respect to the pallet 1, the portion of the belt 41 connected with the connecting member 6 serves as a fixing point to enable the belt 41 to be linearly moved with respect to the first pulley 42 and the second pulley 43. With the above structure, in the process that the first pulley 42, the second pulley 43 and the belt 41 are driven by the driven rack 24 to move linearly as a whole, the belt 41 drives the first pulley 42 and the second pulley 43 to rotate and move linearly relative to the first pulley 42 and the second pulley 43, and the movement stroke of the driven rack 24 can be further enlarged by using the structure (as shown in fig. 1 and 2).

As shown in fig. 1, in the initial state (before the puncture needle 5 is inserted), the secondary transmission assembly 4 and the movable rack 24 are both positioned at the upper part of the supporting plate 1, the puncture needle fixing member 3 is positioned at the upper part of the belt 41 and is close to the first pulley 42, and along with the needle insertion operation of the puncture needle 5, the puncture needle fixing member 3 moves along with the belt 41 and is close to the second pulley 43 (as shown in fig. 2). In this transmission assembly, as shown in fig. 1 and 2, the movement stroke of the belt 41 is twice that of the movable rack 24, i.e., the movement stroke of the belt 41 is four times that of the gear 22. When the gear 22 moves linearly 10mm (i.e., the push rod 26 moves linearly 10 mm), the belt 41 moves linearly 40mm, i.e., the puncture needle 5 advances 40mm. The principle of the transmission assembly for realizing the movement stroke amplification is similar to that of the movable pulley. In this embodiment, the primary transmission assembly 2 amplifies the motion stroke of the linear motor 21 (push rod 26), and the secondary transmission assembly 4 amplifies the motion stroke of the linear motor 21 (push rod 26), and the final amplified motion stroke is four times of the motion stroke of the linear motor 21 (push rod 26).

The utility model achieves the technical effects that the push rod 26 is pushed by the linear motor 21 to linearly move, meanwhile, the gear 22 is driven to linearly move, the gear 22 rotates around the axis under the action of the movable rack 24 and the fixed rack 23, the linear travel of the movable rack 24 is twice as long as that of the gear 22 according to the cooperation of the gear 22 and the movable rack 24, the linear movement of the movable rack 24 drives the first pulley 42 and the second pulley 43 to integrally linearly move, in the process, the linear travel of the belt 41 is twice as long as that of the movable rack 24 according to the cooperation of the belt 41, the first pulley 42 and the second pulley 43, and finally, the linear travel of the puncture needle 5 fixed on the puncture needle fixing piece 3 is four times as long as that of the gear 22, so that the movement travel of the linear motor 21 is amplified, the puncture device can be shorter in length under the condition of meeting the movement travel of the puncture needle 5, and the puncture device is beneficial to achieving miniaturization and portability, and further solving the problem that the puncture device in the related technology cannot amplify the movement travel and the integral length of the device is longer.

In the primary transmission assembly 2, the gear 22 is driven by the push rod 26 to linearly move on the supporting plate 1 and rotate in a fixed shaft. In order to enable the gear 22 to be properly engaged with the fixed rack 23 and the movable rack 24, it is necessary to ensure that the movement of the gear 22 is linear. For this reason, as shown in fig. 1 to 3, the primary transmission assembly 2 in this embodiment further includes a transmission block 25, a first chute 103 is provided on the pallet 1 along the moving direction of the push rod 26, the transmission block 25 is slidably provided in the first chute 103, and the transmission block 25 is fixedly connected with the end of the push rod 26. The transmission block 25 is provided with a rotating shaft 221, the axis of the rotating shaft 221 is perpendicular to the axis of the push rod 26, and the gear 22 is rotatably sleeved on the rotating shaft 221.

Through the arrangement of the first sliding groove 103, the transmission block 25 can perform linear motion along the first sliding groove 103, the first sliding groove 103 plays a role in guiding and limiting the motion of the transmission block 25, the gear 22 is connected with the transmission block 25 through the rotating shaft 221, the gear 22 can keep linear motion consistent with the transmission block 25, and therefore the gear 22 is guaranteed to be correctly meshed with the fixed rack 23 and the movable rack 24. The transmission block 25 and the push rod 26 can be in sleeved connection, a mounting hole can be formed in the transmission block 25, and the push rod 26 is inserted into the mounting hole and fixed. In order to facilitate the connection between the transmission block 25 and the rotation shaft 221, another mounting hole may be formed on the transmission block 25, and the rotation shaft 221 is inserted into and fixed in the mounting hole. The axis of the rotating shaft 221 is perpendicular to the straight line of the push rod 26, and the gear 22 is sleeved on the rotating shaft 221 through a bearing, so that the gear 22 can rotate in a fixed shaft.

The first chute 103 ensures that the motion of the transmission block 25 is linear to some extent, and in order to further ensure that the motion of the transmission block 25 is linear, it is necessary to further prevent the gear 22 from being separated from the fixed rack 23 and the movable rack 24 due to the runout of the transmission block 25 in the first chute 103. For this reason, as shown in fig. 1 and 3, in the present embodiment, first protruding strips 104 are provided on two sidewalls of the first chute 103, and first clamping grooves engaged with the first protruding strips 104 are provided on two sides of the transmission block 25, and the first protruding strips 104 are slidably connected with the first clamping grooves. The first convex strips 104 and the first clamping grooves are matched, so that the transmission block 25 can only move linearly in the first sliding groove 103 along the opening direction of the sliding groove and cannot generate other movements, thereby ensuring the linear movement of the gear 22 and further ensuring the correct meshing of the gear 22, the fixed rack 23 and the movable rack 24.

As shown in fig. 5, the secondary transmission assembly 4 further includes a sliding seat 44, the first pulley 42 and the second pulley 43 are rotatably disposed at two ends of the sliding seat 44, and one side of the sliding seat 44 is fixedly connected with the movable rack 24; the pallet 1 is provided with a second chute 101 in sliding connection with the slide 44.

The slider 44 includes a base plate and ear seats 441 located at both ends of the base plate, and each ear seat 441 is composed of two oppositely disposed ear plates. The first pulley 42 is installed in the lug seat 441 at one end of the base plate through a pin shaft, the second pulley 43 is installed in the lug seat 441 at the other end of the base plate through a pin shaft, and the belt 41 is sleeved on the first pulley 42 and the second pulley 43. The first pulley 42 and the second pulley 43 can also stably rotate on the fixed shaft in the process of linear motion through the arrangement of the lug seat 441.

The ear seat 441 at the upper end of the base plate can be fixedly connected with the first end of the movable rack 24 through a bolt, and the ear seat 441 at the lower end of the base plate can be fixedly connected with the second end of the movable rack 24 through a bolt. The linear motion of the movable rack 24 will drive the sliding seat 44 to move linearly, and since the lower part of the belt 41 mounted on the sliding seat 44 is fixedly connected with the supporting plate 1 through the connecting piece 6, the linear motion of the sliding seat 44 will make the lower part of the belt 41 move linearly with the position of the connecting piece 6 as the fixed end, and simultaneously drive the first pulley 42 and the second pulley 43 to rotate, and simultaneously make the upper part of the belt 41 move linearly, so as to drive the puncture needle fixing piece 3 located at the upper part to move linearly.

Since the sliding seat 44 also needs to ensure that the movement is a straight line, as shown in fig. 1 and 2, the pallet 1 is provided with a second sliding groove 101 in sliding connection with the sliding seat 44, and the movement of the sliding seat 44 can be guided and limited by the second sliding groove 101. On this basis, in order to further prevent the sliding seat 44 from jumping during the movement process, in this embodiment, second raised strips 102 are provided on two side walls of the second sliding groove 101, and second clamping grooves matched with the second raised strips 102 in a clamping manner are provided on two sides of the sliding seat 44, and the second raised strips 102 are slidably connected with the second clamping grooves. The second protruding strip 102 and the second clamping groove cooperate to enable the sliding seat 44 to only move linearly in the second sliding groove 101 along the opening direction of the sliding groove, and cannot generate other movements, so that the linear movement of the sliding seat 44 is ensured.

In the present utility model, the insertion of the puncture needle 5 is finally realized by the belt 41, and the lower part of the belt 41 is required to be relatively fixed with the pallet 1 during the whole movement.
